The Fourier Transform Infrared Spectrometer, Infrared Microscope and XY Scanning Platform were used to establish electrochemical in situ scanning microscopic infrared reflectance spectroscopy by designing and developing in-situ infrared microscopic pool and computer interface and control software. The research shows that this new Spatial resolution in situ IR reflectance spectroscopy not only provides information about the vibrational spectra of the surface micro-domains in the solid / liquid interface but also can be used for infrared imaging of the surface of the electrodes. The chemical map of CO adsorption on Pt polycrystalline electrodes is obtained Like in the 10 -2 cm scale electrode surface micro-area reaction performance of the inhomogeneity and distribution.
